Patent JP-H0318020-A (JP)
Title: Manufacture of semiconductor device
Inventor: TOGASHI MITSUHIRO
IPC: H01L21/285
Filed: 1989-06-14
Abstract: PURPOSE:To prevent the decrease in yield rate due to the generation of particles from a new target by forming plasma in a first vacuum chamber, removing the particles generated from the target, setting the target in a second vacuum chamber, and performing sputtering. CONSTITUTION:A target 2 is connected to a cathode 3. Under this state, the inside of a first vacuum chamber 1 is kept at an approximately vacuum state containing lean argon gas. When a specified voltage is applied across the cathode 3 and an anode 4, plasma is generated, and particles such as ground powder are driven out of the surface of the target 2. Then, the target 2 is connected to the cathode 6 in a second vacuum chamber 5. A substrate 8 is set on an anode 7. A specified voltage is applied across both electrodes 6 and 7. Then, metal atoms are driven out of the target 2, and a thin metal film is formed on the substrate 8. Therefore, in the second vacuum chamber 5, the number of particles generated from one substrate after the replacement of the target becomes constant regardless of the number of substrates in sputtering treatment. Therefore, the yield rate of the substrates in sputtering treatment is not decreased.

Filed: 1984-07-25
Abstract: PURPOSE:To improve the moldability by making the melting viscosity of the resin sealing material suitable by a method wherein the distribution of grain sizes of the filler contained in the resin sealing material is made specific. CONSTITUTION:A portion with a grain size of 2mum or less of the filler 7 contained in the resin sealing material 5 in a resin-sealed type semiconductor device is reduced to 3% or less in accumulative content. For example, a sealing member 5 constituting the sealing package is made of epoxy resin, and only a required amount of the filler 7 composed of melt silica powder or crystal silica is contained therein in order to improve the mechanical strength or the coefficient of thermal expansion or for other purposes. The grain size of this filler 7 is brought into a distribution of grain size as above-mentioned. This manner can prevent the decrease in moldability and the generation of wire bending under an increase in melting viscosity of the sealing member 5 more than necessary.

Title: Electronic switch
Inventor: INOUE KAZUHIRO
IPC: H03K17/60
Filed: 1979-11-27
Abstract: PURPOSE:To enable to ensure on/off of the emitter follower output, by providing the switch which can turn on and off in parallel with the emitter resistance of an emitter follower circuit. CONSTITUTION:When the control voltage Vo is 0 volt, since the diode D1 is backward-biased with the emitter voltage of the transistor and the impedance is infinitive, a capacitor C is separated from the emitter resistance. Thus, the emitter follower circuit performs normal operation and the signal applied to an input terminal 3 appears at the output terminal 4. When the control voltage Vo is increased, the diode D1 is conductive and the emitter voltage is increased to cut off the transistor. Simultaneously, since the emitter is grounded with the capacitor C in AC manner, the signal appeared at the output terminal can surely be cut.
